One of those programs that thinks it knows more about what you want than you do. It my case it starting uploading files to dropbox uninvited and tried to download thousands of files to my PC without even telling me (let alone asking). Options seem to be deliberately hidden within the menu structure (completely unintuitive) and there is no useful documentation. Then when I wanted it to stop uploading unwanted files to dropbox I had to contact three people (over two hours) via their support program before I found somebody who knew how to do it - and it was just check a box through the ridiculous menu system. Avoid!
